ing upward on this terminal. This action is known as creeping and is practically eliminated by my construction as each terminal car ies but a small porportion of the entire capacity of the cell. In the battery illustrated, where there are live plates, each terminal carries but one-fifth of the total capacity of the cell, and thus the action on each terminal is reduced to one-fifth of the total; and, furthermore, the double sealed cover prevents this corrosion working upward and in this way the detrimental creeping is substantially eliminated.

While l have illustrated and described one specific embodiment of my invention, it will, of course, be understood that l do not Wish to limit myself to the exact construction shown and described, as many modifications and changes will readily suggest themselves to those skilled in the art.

Certain features of my invention are disclosed and claimed in my application Serial Number 766,285, filed May 8th, 1913, for improvement in storage batteries, and as to these features I intend that this application shall be a continuation of my earlier application.

What l claim as my invention is:

l. In a storage battery, a series of electrode plates, each having an upwardly ei;- tending rod secured thereto, a containing vessel tor said plates, a cover therefor, said rods passing through said cover, said cover comprising a pair of hard rubber plates, separated by sealing material, both of said plates being sealed in said vessel, connections between said rods at points on said cover, and shoulders on said rods supporting the lower plate.

2. ln a storage battery, a series of cells, each cell comprising a plurality of electrode plates, each plate having an upwardly extending rod extending therefrom, a containing vessel for each of said cells having a cover sealed within said vessel, said rods cxtending through said cover, said cover comprising a pair of hard rubber plates separated by sealing material and reinforcing rods between said cover 'plates extending" in a plane at right angles to said terminal rods,

p and a metallic strip connecting the rods of imanes one polarity of one cell with the rods of the opposite polarity of the succeeding cell.

3. In a storage battery, a series of electrode plates, each having an upwardly extending rod secured thereto, a containing vessel for said plates, a cover therefor, said rods passing through said cover,said cover comprising a pair of hard rubber plates, separated by sealing material, both of said plates beingsealed in said vessel, connections between said rods at points on said cover, shoulders on said rods supporting the lower plate, and reinforcing rods between said cover plates extending. at a plane at right angles to said terminal rods.

4. In a storage battery, a series of electrede plates each having upwardly extending rods secured thereto, a containing vessel for said plates, a cover therefor, said rods passing through said cover, said covercoinprising a pair of hard rubber plates separated by sealing material, and a pair of busbars mounted on top of said cover and secured to the upper end` of said rods, whereby all connections between said plates are made through said bus-bars.

5. In a storage battery, a plurality of cells, each cell comprising a series of positive and negative electrode plates arranged alternately, each of the positive plates having an upwardly' extending rod secured thereto at one end thereof, and each of the negative plates .having an upwardly extending rod secured thereto at the other end thereof, a containing vessel for said cells, a cover therefor', said rods passing through said cover, a bus-bai on top of said cover secured to the rods extending from the positive plates, a second bus-bar connected to the rods extending from the negative plates, each of said bus-bars being provided with a portion insulated from the remainder of said bus-bar, and connecting leads integrally connected to the insulated-portions of said bus-bars.
